| http://www.w3.org/ns/prov#value | - Appropriate sludge conditioning results in: (a) a sufficiently high pH in the reaction zone (near neutral to slightly alkaline) so that hydrogen sulfide is substantially dissociated into nonvolatile ions; (b) a low content of volatile fatty acids and other odorous compounds in the mixed liquor; and, (c) low hydrogen sulfide generation due to the lack of carbon source for sulfate reducing organisms
